Sometimes it is necessary to provide initial configuration information for

Servlets. Configuration information for a Servlet may consist of a string or a set

of string values included in the Servlets web.!ml declaration.

"ou define initiali#ation attributes for servlets in the $eb application

deployment descriptor, web.!ml, in the init%param element of the servlet

element, using param%name and param%value tags. The web.!ml file is located

in the $&'%()* directory of your $eb application.

Create a web application to provide implementation to above according to your

assumption for any such four parameters.

Use a package titled as you first name.

Create a servlet that shows per%client access counts, that shows basic

information about the clients session. $hen the client connects, the servlet

uses request.getSessioneither to retrieve the e!isting session or, if there is no

session, to create a new one. The servlet then loo+s for an attribute called

accessCountof type Integer. (f it cannot find such an attribute, it uses as the

number of previous accesses. This value is then incremented and associated

with the session by setAttribute. *inally, the servlet prints a small HTML table

showing information about the session.

Use a package titled as you first name.
